Formula Column Path name not synched

Steps to reproduce:

1. Generate column with values
2. Generate second colum with values depending on another column
3. Rename first column Current: The values of the second column are not updated, because the name of the first column changed Regenerating does also not work, because the path name is wrong.

Workaround: Regenerate the values but the new Column name must be choosen from the combobox
